At loggerheads

The idiom at loggerheads, which usually functions as a predicate adjective, means in a dispute. Its origins are mysterious. Loggerhead originally referred to a stupid person, and in the 17th century it took a new definition—thick-headed iron tool. When at loggerheads came about soon thereafter, it may have referred to the use of loggerheads as weapons in fights. In any case, at loggerheads (loggerheads is always plural in the idiom) now implies harsh disagreement but not necessarily violence.

The idiom is likely British in origin, and it is used most frequently in British English, but it does appear in all major varieties of English.

The singular loggerhead is mostly archaic. It now appears only in reference to the loggerhead turtle, a species of large sea turtle with a reddish-brown shell.
